Interesting, my two Bloody Skunk Autos I have going are on day 52 about 3 weeks into flower and they stand 32-34" tall and that's growing under a single crappy 300w viparspectra led!
They started flowering around day 30ish or so at about 8 inches tall, don't remember exact but it was around there. They grew a damn near 24-26" in 2-3 weeks after flowering! It was crazy.
@Tazard, not sure sorry! i'm slack, i was gonna check it if issues kept showing but i think i just mixed up a batch of water at a bad ph, after being more careful with subsequent waterings the issues cleared up
